SUMMARY AND DETAILED DESCRIPTION

The present invention provides an article having a base, a base coatingadhered to the base, the base coating being formed from a base coatingcomposition comprising, in approximate volume, the followingingredients:

    ______________________________________                                               Ingredients                                                                           Volume                                                         ______________________________________                                               Hide glue                                                                             14-34                                                                 Colorant                                                                              0.1-2                                                          ______________________________________                                    

and an acrylic polymer paint coating adhered to the base coating, theacrylic coating having checks to provide an antique appearance.

The present invention also provides a method of making theabove-described article, the base coating step being such that thedeposited base coating is of a thickness sufficient to penetrate, atleast slightly, the base and also having a thinness sufficient to causea plurality of small checks in the subsequently formed acrylic paintcoating to thereby provide the article with a desired old, weathered,antique look.

The thickness of the base coating layer is generally about 1/2 or 1 milup to 10 or 12 mils and preferably about 2 to 8 mils. The thickness ofthe acrylic coating is about the same as the base coating or about 1/2to 12 mils and, preferably, 1 to 5 mils.

The base is preferably wood although suitable article bases also arefiberboard, wallboard, cardboard, canvas and other easily shaped anddecorated materials.

The base coating composition preferably has about 22 to 26 volumes ofhide glue and about 0.3 to 1 volume of colorant.

Optionally, water can be used with the hide glue and colorant asfollows:

A preferred base coating composition with water is as follows:

    ______________________________________                                        Ingredients     Volume                                                        ______________________________________                                        Hide glue       24                                                            Water           5                                                             Ink (colorant)  1                                                             ______________________________________                                    

The acrylic polymer paint coating is known in the art. A suitableacrylic coating composition is Delta Acrylic Paint, Delta TechnicalCoating, Inc., Whittier, Calif. Acrylics include polymethylmethacrylate,polyethylmethacrylate, polymethylethacrylate and polyacrylic acid as setforth, for instance, in Modern Plastics Encyclopedia, 1981-82, pages9-10.

Generally, the acrylic coating composition comprise a short chain,further polymerizable, curable acrylic polymer in a solvent such asstyrene or other copolymerizable monomes that also provide crosslinkingin the resultant polymer. Suitable pigments, stabilizers, catalysts andadditives may be used as is known.

Suitable hide glues, that are impure gelatin solutions, are thoseobtained from boiling animal hides. Hide glues are disclosed, forinstance, in U.S. Pat. No. 2,513,121. Hide glues often have apH of about5.8 to 7.4, the glues being in solution in water, and the glue may rangefrom about one part glue to one part water to about one part glue to 3or 4 parts water. The percent by weight of glue solids can be from about5 to 50%.

A suitable hide glue can be obtained from Franklin Hide Glue, FranklinInternational, Columbus, Ohio.

A suitable colorant is a black ink containing carbon black, shellac,borax and water. A suitable black ink, Black Ink No. 416, can beobtained as Carter's Ink, Black No. 416, from the Dennison ManufacturingCompany, Framingham, Mass.

When an ink is used as the colorant, the pigment, (preferably carbonblack) is about 10 to 50 or 60 parts by volume of the aqueous inksolution. In general, the pigment is about 5 to 10 up to 50 or 60 weightpercent of the aqueous ink composition. As is known, other inkingredients such as borax and shellac can be used.

The colorant and hide glue can be mixed just prior to coating the basewith the base coating composition, or the colorant, and hide glue can bepremixed and stored, for some time, before coating.

The colorant can be an inorganic or organic pigment or dye. The colorantcan be dry or liquid and is preferably water soluble and compatible withwater and the hide glue. Suitable colorants are carbon black, boneblack, iron oxide, titanium dioxide, aniline black, ultramarine blue,zinc oxide and other metallic pigments, such as aluminum and bronzepowders. As is known, pigments often generally have an average particlesize of about 0.01 to 1 micros.

Colorants and pigments are known in the art and disclosed, for instance,in Modern Plastics Encyclopedia, 1981-82, pages 146-166.

As previously described, the amount of colorant used is relatively highfor the superior results of good base coloring and the formation of manyfine checks in the overcoating. The high amount of colorant, 0.7 to 2volumes per 14 to 34 volumes of hide glue, is many times (preferably atleast 20 to 30 times) higher than the amount of colorant in any previoususe (1 part of colorant (inf) per 700 parts of volume of hide glue.

The thickness of the base is not critical and generally is about 1/16inch to 1/4 or 1/2 inch.

In another embodiment, the hide glue can be substituted in whole or partby an animal glue including bone glue and mixtures thereof with hideglue. Bone glue, when used, is highly preferred.

As is known, animal glue is obtained by boiling hides and by boilingbones of animals, the animal glue (impure gelatin solutions) being hideglue, bone glue, and gelatin.
